CAUTION
● Never run pump dry or shut off a suction valve during operation. Otherwise the pump
fails in a short period.
● Check the rotational direction of the pump. Clockwise seen from the motor end is a
correct direction. Operation in the reverse direction may cause pump damage. Always
carry out rotation check with the pump full of liquid.
● Stop the pump within one minute if cavitation occurs.
● Do not run the pump when air enters the suction line.
● Stop the pump immediately when the magnet coupling is disconnected. The magnet
force reduces if the pump keeps on running for more than one minute in this condition.
● The maximum number of ON/OFF operation should be within six times an hour.
Frequent ON-OFF operation can reduce the pump life.
● Keep liquid temperature change within 80 ˚ C through operation and stopping.
● Start the pump with a discharge valve full close in order to avoid water hammer.
● Closed-discharge operation should be within one minute. If the pump runs with a dis-
charge valve closed for a long time, the liquid temperature inside the pump rises and
it damages the pump.
● If power is interrupted when the pump is running, switch off and close a discharge
valve.
● Take extra care so that the discharge pressure does not exceed the pump limit.
● When high temperature liquid is transferred, the pump surface becomes very hot.
Take a protective measure against burn. See below.

● Noise level is 90dB (A scale - one meter)
In case the pump noise affects human health or the communication to secure a safety,
provide a noise reduction cover. Be careful not to reduce cooling effect by a motor fan.
